Mooring integrity monitoring

Mooring line and anchor leg integrity is an area of concern with failures still all too common. Our subsea systems can monitor mooring lines continuously, detecting and reporting failures as they occur, allowing the safe management of the facility.

Mooring line monitoring system

Maintaining mooring line integrity for offshore production and storage facilities is a key element for safe operations. By using SMART sensors, mooring line or anchor legs can be constantly monitored to ensure no line breaks have occurred. Using integrated internal high accuracy pressure sensors and six degrees of freedom IMUs, anchor breaks, both above or below the SMART, can be quickly identified and reported to the topside control room.

SMART operations

By using efficient wireless acoustic telemetry each mooring line-located SMART can transmit statistical information to the surface transceiver giving its position, depth and movement. As a cable-free arrangement, SMART is cost-effective to install and operate.

Surface located transceivers, such as the Dunker 6 or an HPT – which may form part of an existing vessel or rig acoustic equipment installation – can be used to harvest data from the SMARTs at any user-defined interval or on-demand. A range of deployment systems can be supplied either as over-the-side or more permanently mounted on a through-hull arrangement with gate valve.

BOP fatigue and bop anchor monitoring

As BOPs have increased in size, we have developed complimentary technologies and sensors to address two important challenges. SMART systems can accurately monitor BOP accelerations and rotations, to help operators ensure that wellhead fatigue is within safe working limits.

SMARTs can also be configured to act as a recording, processing and telemetry system for BOP tension monitoring systems. Using SMARTs in this configuration provides a way to monitor the securing line tension, record static and dynamic load, and transmit already processed, user-ready data to a drilling or surface vessel on demand. Ordinarily data is read from load pins located either at the rigging point on the BOP or at the rigging point on the seabed located pile.
